What sorting algorithm needs a pivot element to partition unsorted list? Insertion Sort Merge Sort Selection Sort O Quick Sort

Using the first value in the appropriate lists as the pivot value, sort the same list of numbers using the quick sort: 13 9 5 7 12 2 3 14 6 1  (no code, just handwritten showing of sorted steps)

53: What sorting algorithm is this? void Sort1(string arr[], int beg, int end) { int piv index = subdivision(arr, beg, end); if (piv_index-1 > beg) { Sort1(arr, beg, piv_index-1); } if (piv_ind+1 piv) down--; if (up <= down) { tmp = arr[up]; arr[up] = arr[down]; arr[down] = tmp; up++; down --; } arr[beg] = arr[down]; arr[down] = piv; return down; %3D

Selection sort algorithm is ________, the worst case time complexity of sorting an array containing N elements with selection sort is              . Group of answer choices stable, O(N) stable, O(N2) unstable, O(N2) unstable, O(N)
